The UVC disinfection method
It is a global obligation to ensure a healthy environment. The UVC disinfectionmethod is a topical process to take care of the health of your employees, your customers and your loved ones. Devices PuriTechs fight the spread of viruses and bacteria in all professional environments where hygiene and cleanliness are of the utmost importance.
In light of the current pandemic, PuriTechstechnology allows the disinfection of airand surfaces using the principle of UVC radiationto reduce and control the spread.
What are UVC rays?
Ultraviolet (UV) is an energy that is found in the electromagnetic spectrum, specifically between X-rays and light visible to the naked eye. Although UV rays are not perceptible to the human eye, we are exposed to them every day through the sun’s rays, which are composed of UV light and are responsible for our sunburns. UV rays can be categorized into three categories: UVA, UVB and UVC.
The latter, although very effective, are the most energetic and harmful UVs of the three. It is therefore necessary to take precautions and to use products specifically designed for the use of UVC radiation.
+++ ...Indeed, from a medical point of order, UVC radiation are known to reduce bacteria and viruses that may be harmful and pose a health risk. To ensure optimal results, they must be used according to the strictest procedure.
What is the UVC disinfection method?
The germicide ultraviolet radiation (UVC) is the method of disinfection used by PuriTechs. It kills or inactivates microorganisms by destroying their nucleic acids, which alters their DNA and RNA. As a result, they are unable to be harmful and reproduce. The germicide ultraviolet radiation can be used in a multitude of applications, such as food, air or water.
+++ ... UVC disinfectionhas the advantage of being able to take place in a variety of professional environments, such as hospitals, transport, gyms, shops, changing rooms, laboratories or waiting rooms. It is also capable of disinfecting professional equipment, including safety glasses, instruments, pipettes and other devices. Indeed, research laboratories use this disinfection process for glass and plastic of their material.
In fact, several studies have shown the effectiveness of decontamination through germicide ultraviolet radiation H1N1, as well as SARS-CoV-2, the virus that introduces Covid-19 to the medical community (1,2). Indeed, the results showed a reduction and significant control of the spread of the virus. This therefore provides an interesting gateway for larger environments such as restaurants, hotels, or airplanes.
How does the UVC disinfection method work?
The disinfection of air or surfaces is done by the use of germicidal lamps that will diffuse UVC with a wavelength of 254 nanometers. When a microorganism is exposed to UVC, the cell nucleus is modified under the effect of the photolytic process, which will prevent cell division and therefore, reproduction.
+++ ...Several factors are to be noted for optimal effectiveness of germicidal ultraviolet radiation:
- The duration of exposure of a microorganism;
- The intensity of exposure to UVC radiation;
- The wavelength of UVC radiationused.
It is also necessary to take into account the presence of potential particles that can protect microorganisms from UV or the ability of a microorganism to resist UVC.
For some bacteria, the dose ofUVC used will not immediately cause the cell to be destroyed, but rather to deactivate it. That is, there will still be biological activity, but it will no longer be viable. However, there is the possibility of increasing the efficiency and intensity of UVC using the method of reflection. By using aluminium, the rate of reflection will be all the more important and therefore more effective when using UVC radiation.
PuriTechs products for UVC disinfection
PuriTechs propose aux magasins, aux hôpitaux, aux hotels, aux restaurants, aux transports, aux salles de sport ou tout autre endroit professionnel, une décontamination efficace et rapide. Par sa technologie de rayonnement ultraviolet germicide, celle-ci peut désinfecter en même temps l’air et les surfaces touchés par le rayonnement UVC.
+++ ...Les dispositifs PuriTechs produisent suffisamment de lumière germicide dans les systèmes de circulation d’air ou sur tous types de surface, et rendent les environnements hostiles aux micro-organismes, tels que les bactéries, les virus, les moisissures et d’autres agents pathogènes.
Pour garantir une mobilité et une utilisation optimales, PuriTechs met à disposition deux produits performants :
- The Tube, directement installé sur des roues pour pouvoir se déplacer facilement à travers les espaces à décontaminer. Il fonctionne via une application mobile afin de protéger l’utilisateur au maximum ;
- The Box, installé sur des roues pour permettre une meilleure mobilité, ses lampes sont disposées dans un caisson antichoc, rayonnent sans obstacle dans l’espace et en toute sécurité. Après son utilisation, l’appareil peut être facilement rangé dans un coin de la pièce.
La décontamination de l’air et des surfaces par traitement UVC se compare favorablement à d’autres systèmes de désinfection en matière de coûts et de main-d’oeuvre. En effet, une fois activés, les produits PuriTechs peuvent désinfecter très rapidement un restaurant, ou un avion sans l’intervention humaine.
Philips technology against Covid-19
For more than 100 years, the world’s leading lighting company has been synonymous with quality and energy efficiency. That’s why PuriTechs Philips technology and European manufacturing.
It is important to note that the intensity of the UVC is inversely proportional to the distance to the square, so the intensity decreases when the distances are longer. Nevertheless, thanks to the power of Philips germicidal light, PuriTechs are capable of decontaminating a space in record time.
+++ ...According to studies conducted on Philips technology (by the Signify group) against Covid-19, the power of germicide ultraviolet radiation allows the destruction of the SARS-CoV-2 virus at 99.9% over a distance of 1.25 meters in just 15 seconds of irradiation. (3,4) With these devices, an exposure of 90 seconds at a distance of 2 meters would thus be enough for a 99.9% eradication of the SARS-CoV-2 virus, which causes Covid-19 PuriTechs.
We thus guarantee the development of powerful and efficient products to be able to face the latest global health developments and to help the professional world.
